OIL-CUP FOR PLANES.

Specification of Letters Patent.

Patented Nov. 16, 1909.

Application filed June 22, 1907. Serial No. 380,239.

To all whom it may concern:

Be it known that I, DAVID JAMns, citizen of the United States, residingat Gofieyville, in the county of Montgomery and State of Kansas, haveinvented new and useful Improvements in Oil-Cups for Planes, of whichthe following is a specification.

My invention relates to improvements in oilers for planes.

The object of my invention is to provide a device of the characterdescribed, in which the lower face of the plane can be supplied with theproper amount of oil, and by which the oil supply opening can not befilled with dirt and prevent the proper operation of the oiler. Neitherwill the oil run from the oil cup when the plane is inverted.

Another object of myinvention is to provide a more simple, cheap andeffective oiler of this character to accomplish the result desired.

In the accompanying drawings: Figure l is a longitudinal verticalsectional view of a plane, showing my improved oiler applied thereto;Fig. 2 is a top plan view of the plane partly broken away; and Fig. 3 isan enlarged detached view of the valve showing the several parts removedor separated from each other.

Referring now to the drawings, 1 repre sents a plane which is of theordinary structure and having the usualboss 2 adjacent its forward endto which is attached an ordii nary knob 3 for operating the same. In myimproved oiler, this knob forms the oil cup, and, as shown, is of aspherical shape and hollow so as to receive and hold the oil. As shown,the boss 2 is externally screwthreaded and the oil cup provided with aninternally screw-threaded opening 4, which is screwed upon the boss. Thesaid boss is provided with a central opening 5 which extends through thelower face of the plane 6 and through which the oil 'passes to the lowerface of the plane. The oil cup has an inwardly extending flange 7 whichextends over the upper end of the boss and is provided with an opening 8corresponding with the opening 5 in the boss. The said opening, at itsupper end, is provided with an annular flange 9, the lower face of whichforms the seat for the valve, as will be hereinafter more fullydescribed.

The upper end of the oil cup is provided with an enlarged opening 10through which the oil is placed in the cup and in which the openingwithin the flange 9 and below the same has rigidly secured thereto avalve 12, which, as shown, is of a circular form and fits firmly againstthe lower face of the flange 9 and forms a tight joint to prevent theescape of oil from the cup. The stem 11, adjacent its upper end, isscrew-threaded and screwed thereon is a nut 13. Coiled upon the stem,below the nut, is a coilspring 14 which has its lower end bearing uponthe flange 9 and normally forces the valve stem upwardly and holds thevalve firmly to its seat.

Screwed upon the extreme upper screwthreaded end of the valve stem is ahead 15 which is of a size approximating that of the opening 10 and isprovided with a reduced externally threaded sleeve 16- extending withinthe oil cup. Carried by this sleeve is a washer 17, preferably ofleather, which engages the walls of the opening 10 and prevents the oilfrom leaking therefrom. Below the washer and carried by the sleeve is anut 18 which adapted to expand the washer and insure a perfectfit withthe walls of the openings.

In order to prevent the screw-head from turning and accidentaldisplacement from the valve stem, I provide the upper face of the oilcup, adjacent the opening 10, with an annular recess 19, having ascrew-thread; ed opening into which is screwed a flatheaded screw 20,and the screw-head 15 is provided with a recess 21 into which theflat-headed screw 20 extends and prevents the head from turning. Thehead of the screw has a curved cut-away portion 22 which, when turned inits proper position, allows the head to be turned.

The valve stem 11 has its lower end screwthreaded at 23 and screwedthereon is a sleeve nut 24:, the head portion of which fills the opening5 in the boss and prevents the dirt, etc., from filling this opening 5.By turning this nut, it will be seen that the same can be adjusted sothat it will hit a slight distance above the lower face 6 of the plane.

By pushing upon the screw-head, it will be seen that the valve stem isforced downwardly against the tension of the spring and the valve isunseated. The sleeve nut is likewise carried downwardly clearing theopening 5 of all the dirt and allows the oil to freely flow downwardlyto the lower face of the plane. When the screw-head is released, itresumes its normal position and should the plane be inverted no oil willleak therefrom.

Having thus fully described my invention, what I claim as new and desireto secure by Letters Patent, is:

1. The combination with a plane, of an oil cup attached to the upperface of the plane and in communication with the lower face of the plane,a valve controlling the flow of oil from the cup, and a plug carried bythe valve for preventing the communication from being filled with dirt.

2. The combination with a plane, of an oil cup attached to the upperface of the plane and in communication with the lower face of the plane,the cup having a filling opening therein, a valve controlling the upperend of the lower communication, a plug carried by the valve for closingthe lower end of said openin a valve stem carried by the valve andextending within the filling opening, and a head within the fillingopening for closing the same and adapted to operate the valve stem.

3. Tie combination with a plane, of an oil cup attached to the upperface of the plane and in communication with an opening through theplane, the oil cup having a filling opening, a head closing said openingand having a screw-tl'ireaded sleeve extending within the oil-cup, anelastic washer carried by the sleeve and engaging the walls of thefilling opening, a nut on said sleeve for expanding the washers, a valvestem screwed within the sleeve, a valve carried by the stem andcontrolling the opening through the plane, and means carried by the stemfor preventing the last named opening from being filled with dirt.

t. The combination with a plane, of an oil cup attached to the upperface of the plane and in communication with an opening through theplane, the oil-cup having a filling opening, a head closing said openingand having a recess in its upper face, a screw carried by the oil-cupand having its head extending within the recess, the said head having acut-away portion to corresponcl with the curvature of the screw-head, asleeve carried by the head and extending within the oil cup, an elasticwasher carried by the sleeve and engaging the walls of the fillingopening, a nut on said sleeve for expanding the washer, a valve stemscrewed within the sleeve, a flange surrounding the opening through theplane and forming a valve seat on its lower face, a

valve carried by the stem, a spring surrounding the stem between thesleeve and the flange and normally holding the valve stem upward withthe valve seated, and a screw sleeve screwed upon the lower end of thevalve stem and normally filling the lower end of the opening extendingthrough the plane for preventing the same from being filled with dirt.

5. The combination with a plane, of an oil cup attached to the upperface of the plane and in communication with the lower face thereof, avertically disposed valve stem within the oil cup and having a valvecarried thereby and working in combination with a valve seat within thecup, and a plug carried by the lower end of the valve stem and closingthe communication between the oil cup and the lower face of the plane.

The combination with a plane, of an oil cup attached to the upper faceof the plane and in communication with the lower face thereof, avertically disposed valve stem within the oil cup and having a valvecarried thereby and working in combination with a valve seat within thecup, a valve stem carried by the valve and extending into the fillingopening, a head closing the filling opening and adapted to operate thevalve stem, a plug carried by the lower end of the valve stem within thecommunication between the oil cup and the lower face of the plane, andmeans connected to the valve stem for normally holding it in an upwardposition with the plug flush with the lower face of the plane.

In testimony whereof I have affixed my signature, in presence of twosubscribing witnesses.
